Some of our employees here at ThinkGeek World Domination HQ are young enough that they don’t remember these on trees from holidays long past. These “bubble lights” were incredibly popular in the 50s and 60s. Basically, the light heats up a little vial of methylene chloride (boiling point 103.3° F) which bubbles away, creating a mesmerizing visual effect.
It’s chemistry in action! When they’re all bubbling, they remind us of something you might see in a mad scientist’s lab. And then we thought, “Wait. It’s also like magic.” Can’t you see some sorcerer or wizard busily brewing a new potion to sell to foolhardy adventurers? So we decided to put our own spin on these by creating our own version with seven little potion bottles bubbling away, perfect for the aspiring magic user.
As with any magical substance, keep these away from pets and small children. Instructions for neutralizing methylene chloride spills are included in case one breaks. The amount of chemical in one bulb is small (specifically 0.09 fl. oz. – not enough to cause serious poisoning), but do not take chemistry lightly.
